Benzer şekilde `/users/{user_id}` gibi tanımlanmış ve belirli bir kullanıcı hakkında veri almak için kullanıcının ID bilgisini kullanan bir yolunuz da mevcut olabilir.

*Yol operasyonları* sıralı bir şekilde gözden geçirildiğinden dolayı `/users/me` yolunun `/users/{user_id}` yolundan önce tanımlanmış olmasından emin olmanız gerekmektedir:

# Модель Pydantic
class User(BaseModel):
    id: int
    name: str
    joined: date
```

Это можно использовать так:

```Python
my_user: User = User(id=3, name="John Doe", joined="2018-07-19")

second_user_data = {
    "id": 4,
    "name": "Mary",
    "joined": "2018-11-30",
}

my_second_user: User = User(**second_user_data)
```

/// info | Информация

    return user_id


# Un modelo de Pydantic
class User(BaseModel):
    id: int
    name: str
    joined: date
```

Que luego puede ser usado como:

```Python
my_user: User = User(id=3, name="John Doe", joined="2018-07-19")

second_user_data = {
    "id": 4,
    "name": "Mary",
    "joined": "2018-11-30",
}

my_second_user: User = User(**second_user_data)
```
